Abstract
This disclosure concerns an interactive head-mounted eyepiece with an integrated processor for handling content for display and an integrated image source for introducing the content to an optical assembly through which the user views a surrounding environment and the displayed content and a light source that directs light to a curved polarizing film of the optical assembly that reflects a portion of the light to illuminate a reflective image display. The optical assembly comprises an optically flat film that reflects the image light from the reflective image display to a curved partially reflecting mirror that reflects a portion of the image light and transmits a portion of the scene light from a see-through view of the surrounding environment, so that a combined image comprised of portions of the reflected image light and the transmitted scene light is transmitted through the optically flat film and provided to the user's eye.
